In comparison with conventional pan mixers (horizontal or vertical shaft), the Reich TURBO Mixer employs a number of special features:
The rotating TURBO mixing drum lifts the aggregate materials by means of side-mounted vanes. Materials are conveyed and mixed with a minimum of friction. Very little friction occurs along the interior of the drum to the final mixing area.
The mixing elements mounted on a central shaft are rotating to the opposite direction and ensure a through intermingling of the aggregates without driving them against the walls or even the reinforced section (an effect which is unavoidable with the conventional mixer types).
Friction consuming energy and causing heat is largely avoided. Generous distances between the mixing elements and the drum head and walls of the mixing drum prevent clogging and crushing of aggregates or mix that has set hard, even with large aggregate sizes.
The central paddle shaft is equipped with an oil-filled labyrint type single shaft seal. Instead of several sealings, TURBO requires only one. In addition with its innovative seal, this design dramatically decreases cost for spare parts as well as down-time for maintenance.
The Reich TURBO Mixer is particularly suitable for mixing dry (low slump) constituents. It is equally reliable for producing concrete to grades BI and B II, as well as mixes containing coarse crushed aggregates up to 200 mm size and any type of lightweight and non-standard concrete mixes.
The chosen mix-specification is maintained without variations, since the TURBO MIXER does not break or crush the material in any way which normally increases the surface area and content of fines of the mix. In addition, the process does not produce any rise in the mix temperature, which is unavoidable with pan mixers.
The circumferential speed of the mixing tools in all types of TURBO MIXER is less then 2 m/sec, which so is the ideal range for mixing speeds. Pan mixers only work with this mixing speed in a very small area, since their mixing speed ranges from almost 0 (middle) up to 4 m/sec or more (at the pan wall), depending on diameter.
The combination of these beneficial features contribute to a reduction in wear, enabling Reich to offer mixers capable of prolonged, trouble-free service life and much lower operational cost, less down-time for maintenance etc.
In addition, the exceptionally low energy requirement for the mixing and discharging process of the Reich TURBO Mixer guarantee savings of 40-50 % in comparison with conventional types of mixer.
With its compact configuration, the TURBO Mixer allows mixing plants to be built with an hourly capacity well beyond the output of conventional mixing plants. Supplied in a steel frame, the TURBO Mixer can ideally be integrated into any existing mixing plant adapting to all requirements.
